Definitions

Dispersin: The term “dispersin” and the abbreviation “Dsp” means a polypeptide having hexosaminidase activity, EC 3.2.1.- that catalyzes the hydrolysis of β-1,6-glycosidic linkages of N-acetyl-glucosamine polymers (poly-N-acetylglucosamine) found e.g. in biofilm.

Hexosaminidase: The term “hexosaminidases” means a polypeptide having hexosaminidase activity (hexosaminidases), and includes EC 3.2.1.e.g. that catalyzes the hydrolysis of N-acetyl-D-hexosamine or N-acetyl-glucosamine polymers found e.g. in biofilm. The term includes dispersins and includes polypeptides having N-acetylglucosaminidase activity and β-N-acetylglucosamininidase activity. The term “polypeptide having hexosaminidase activity” may be used interchangeably with the term hexosaminidases and similar the term “polypeptide having β-N-acetylglucosaminidase activity” may be used interchangeably with the term β-N-acetylglucosamininidases. For the purposes of the present invention, hexosaminidase activity is determined according to the procedure described in Assay 1 or 2. In one aspect, the polypeptides of the present invention have at least 20%, e.g., at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 100% of the hexosaminidase activity of the mature polypeptide of SEQ ID NO 2.

Allelic variant: The term “allelic variant” means any of two or more alternative forms of a gene occupying the same chromosomal locus. Allelic variation arises naturally through mutation, and may result in polymorphism within populations. Gene mutations can be silent (no change in the encoded polypeptide) or may encode polypeptides having altered amino acid sequences. An allelic variant of a polypeptide is a polypeptide encoded by an allelic variant of a gene.

Biofilm: A biofilm may be produced by any group of microorganisms in which cells stick to each other or stick to a surface, such as a textile, dishware or hard surface or another kind of surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides. Biofilms may form on living or non-living surfaces. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism, which, by contrast, are single-cells that may float or swim in a liquid medium. Bacteria living in a biofilm usually have significantly different properties from planktonic bacteria of the same species, as the dense and protected environment of the film allows them to cooperate and interact in various ways. One benefit of this environment for the microorganisms is increased resistance to detergents and antibiotics, as the dense extracellular matrix and the outer layer of cells protect the interior of the community. On laundry and hard surfaces biofilm producing bacteria can be found among the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp Micrococcus luteus, Pseudomonas sp., Streptococcus sp., Streptococcus dysgalactiae, Staphylococcus epidermidis, Staphylococcus aureus, Staphylococcus pneumoniae, Stenotrophomonas sp., Enterobacter sp., Xanthomonas sp., Yersinia sp., Klebsiella sp., Burkholderia sp., Stenotrophomonas sp., Variovorax sp., Escherichia sp., Raistonia sp., Achromobacter sp., Luteibacter sp., Citrobacter sp., Xanthomonadaceae sp., Halomonas sp., Bordetella sp., Lysobacter sp., Serratia sp., Escherichia sp., Aggregatibacter sp., Listeria monocytogenes, Clostridium difficile, Mycobacterium sp., Neisseria gonorrheae, H. influenzae, Haemophilus ducreyi, Helicobacter pylori, Campylobacter jejuni and Enterococcus faecalis as well as the fungi Candida albicans, Aspergillus flavus, Fusarium solani, and Cryptococcus neoformans. In one aspect, the biofilm component e.g. poly-N-acetylglucosamine comprising strain is Brevundimonas sp. In one aspect, the biofilm component e.g. poly-N-acetylglucosamine comprising strain is Pseudomonas alcaliphila or Pseudomonas fluorescens. In one aspect, the biofilm component e.g. poly-N-acetylglucosamine comprising strain is Staphylococcus aureus.

Catalytic domain: The term “catalytic domain” means the region of an enzyme containing the catalytic machinery of the enzyme.

cDNA: The term “cDNA” means a DNA molecule that can be prepared by reverse transcription from a mature, spliced, mRNA molecule obtained from a eukaryotic or prokaryotic cell. cDNA lacks intron sequences that may be present in the corresponding genomic DNA. The initial, primary RNA transcript is a precursor to mRNA that is processed through a series of steps, including splicing, before appearing as mature spliced mRNA.

Clade: a group of polypeptides clustered together based on homologous features traced to a common ancestor. Polypeptide clades can be visualized as phylogenetic trees and a clade is a group of polypeptides that consists of a common ancestor and all its lineal descendants (FIG. 1). The polypeptides of the invention e.g. all belong to the Terribacillus clade, which is illustrated as a phylogenetic tree in FIGS. 1 and 3. The Terribacillus clade or clade of Terribacillus is a group of enzymes all related to the same ancestor and share common properties. Polypeptides forming a group within the clade (a subclade) of the phylogenetic tree can also share common properties and are more closely related than other polypeptides in the clade.

Coding sequence: The term “coding sequence” means a polynucleotide, which directly specifies the amino acid sequence of a polypeptide. The boundaries of the coding sequence are generally determined by an open reading frame, which begins with a start codon such as ATG, GTG, or TTG and ends with a stop codon such as TAA, TAG, or TGA. The coding sequence may be a genomic DNA, cDNA, synthetic DNA, or a combination thereof.

Control sequences: The term “control sequences” means nucleic acid sequences necessary for expression of a polynucleotide encoding a mature polypeptide of the present invention. Each control sequence may be native (i.e., from the same gene) or foreign (i.e., from a different gene) to the polynucleotide encoding the polypeptide or native or foreign to each other. Such control sequences include, but are not limited to, a leader, polyadenylation sequence, propeptide sequence, promoter, signal peptide sequence, and transcription terminator. At a minimum, the control sequences include a promoter, and transcriptional and translational stop signals. The control sequences may be provided with linkers for the purpose of introducing specific restriction sites facilitating ligation of the control sequences with the coding region of the polynucleotide encoding a polypeptide.

The detergent composition may be used to e.g. clean textiles for both household cleaning and industrial cleaning. The terms encompass any materials/compounds selected for the cleaning composition desired and the form of the product (e.g., liquid, gel, powder, granulate, paste, or spray compositions) and includes, but is not limited to, detergent compositions (e.g., liquid and/or solid laundry detergents and fine fabric detergents; fabric fresheners; fabric softeners; and textile and laundry pre-spotters/pretreatment). In addition to containing the polypeptide of the invention, the composition may contain one or more additional enzymes (such as proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidases, haloperoxygenases, catalases and mannanases, or any mixture thereof), and/or detergent adjunct ingredients such as surfactants, builders, chelators or chelating agents, bleach system or bleach components, polymers, fabric conditioners, foam boosters, suds suppressors, dyes, perfume, tannish inhibitors, optical brighteners, bactericides, fungicides, soil suspending agents, anti-corrosion agents, enzyme inhibitors or stabilizers, enzyme activators, transferase(s), hydrolytic enzymes, oxido reductases, bluing agents and fluorescent dyes, antioxidants, and solubilizers.

Enzyme Detergency benefit: The term “enzyme detergency benefit” is defined herein as the advantageous effect an enzyme may add to a detergent compared to the same detergent without the enzyme. Important detergency benefits which can be provided by enzymes are stain removal with no or very little visible soils after washing and/or cleaning, prevention or reduction of redeposition of soils released in the washing process (an effect that also is termed anti-redeposition), restoring fully or partly the whiteness of textiles which originally were white but after repeated use and wash have obtained a greyish or yellowish appearance (an effect that also is termed whitening). Textile care benefits, which are not directly related to catalytic stain removal or prevention of redeposition of soils, are also important for enzyme detergency benefits. Examples of such textile care benefits are prevention or reduction of dye transfer from one fabric to another fabric or another part of the same fabric (an effect that is also termed dye transfer inhibition or anti-backstaining), removal of protruding or broken fibers from a fabric surface to decrease pilling tendencies or remove already existing pills or fuzz (an effect that also is termed anti-pilling), improvement of the fabric-softness, colour clarification of the fabric and removal of particulate soils which are trapped in the fibers of the fabric or garment. Enzymatic bleaching is a further enzyme detergency benefit where the catalytic activity generally is used to catalyze the formation of bleaching components such as hydrogen peroxide or other peroxides.

Expression: The term “expression” includes any step involved in the production of a polypeptide including, but not limited to, transcription, post-transcriptional modification, translation, post-translational modification, and secretion.

DETAILED DESCRIPTION OF THE INVENTION

Various enzymes have been used in laundry many of which relate to removal of malodor. WO2014/087011 describes the use of a deoxyribonuclease (DNase) for reducing malodor from laundry and/or textile, WO9909143 describes the use of one or more oxidoreductases in combination with a mediator for the reduction of malodor and WO2012/112718 describe a method for inhibiting production of laundry malodor caused by bacteria by using various strains of Bacillus. The present invention relates to polypeptides and cleaning e.g. detergent compositions comprising polypeptides from the Terribacillus clade of GH20 family of polypeptides having hexosaminidase activity. Also claimed are laundering methods and the use of the polypeptides with hexosaminidase activity. The polypeptides from the Terribacillus clade of GH20 family with hexosaminidase activity are useful in reducing and preventing staining of items being washed. The inventors have surprisingly found that the polypeptides of the Terribacillus clade of GH20 family having hexosaminidase activity are useful for reduction of laundry associated organic matter e.g. EPS and or PNAG. WO200406117 describes compositions comprising dispersins e.g. DspB. The composition may include a detergent which may be anionic, cationic, or non-ionic. WO9850512 describes enzymes having hexosaminidase activity. The polypeptides of the present invention have hexosaminidase activity however, these do not belong to the DspB clade or to is related to any of the enzymes described in WO9850512. The polypeptides of the invention belong to the Terribacillus clade and are thus distinct from the DspB and from those disclosed in WO9850512. It was therefore surprising that the polypeptide of the invention could be used for prevention, reduction and/or removal of organic matter such as biofilm components e.g. polysaccharides e.g. PNAG (poly-N-acetylglucosamine) on hard surfaces as well as in laundry. There is no indication in the art of the use of hexosaminidases in cleaning processes such as laundry or in detergent compositions comprising e.g. builders and/or bleaches. To be useful in cleaning processes the enzymes need to perform its action in detergents under the conditions of cleaning processes such as laundry, which includes stability in the presence of detergent components such as surfactants, builders and bleach components. The components of a detergent may significantly effect on the performance of the enzymes such as the hexosaminidases. The present application surprisingly shows that polypeptides belonging to the Terribacillus clade are particularly stable in the present of surfactant linear alkylbenzenesulfonates (LAS) which is a very common surfactant in detergents. The polypeptides belonging to the Terribacillus are thus particularly useful for deep cleaning e.g. of textiles or washing machines.

An overview of the Terribacillus clade is provided in FIG. 1. The Terribacillus clade comprises homologous sequences. The polypeptides with hexosaminidase activity of the present invention having the mature amino acid sequences SEQ ID 7, 8 and 9 can be pairwise aligned using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453). The percent identities resulting from such alignments are shown in Table 1 below.

The polypeptides comprising the amino acids sequences of SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9, SEQ ID NO 10 and SEQ ID NO 11 belongs to a subclade of the Dispersin clade. These polypeptides share more than 90% pairwise sequence identity and are closer related to each other compared to e.g. the DspB polypeptides which lies further away (not shown).

A further domain, preferably shared by the polypeptides of the invention, was identified. This domain has not been described previously, the domain is termed IAS and polypeptides of this domain are in addition to having hexosaminidase activity e.g. PNAG activity, characterized by comprising certain motifs e.g. one or more of the [EQ][NRSHA][YVFL][AGSTC][IVLF][EAQYN][SN] (SEQ ID NO 19), corresponding to ESYAIAS at position 44 to 50 of SEQ ID NO 9.

Sources of Hydrogen Peroxide

Suitable sources of hydrogen peroxide are inorganic persalts, including alkali metal salts such as sodium percarbonate and sodium perborates (usually mono- or tetrahydrate), and hydrogen peroxide-urea (1/1).

Sources of Peracids

Peracids may be (a) incorporated directly as preformed peracids or (b) formed in situ in the wash liquor from hydrogen peroxide and a bleach activator (perhydrolysis) or (c) formed in situ in the wash liquor from hydrogen peroxide and a perhydrolase and a suitable substrate for the latter, e.g., an ester.

a) Suitable preformed peracids include, but are not limited to, peroxycarboxylic acids such as peroxybenzoic acid and its ring-substituted derivatives, peroxy-α-naphthoic acid, peroxyphthalic acid, peroxylauric acid, peroxystearic acid, ε-phthalimidoperoxycaproic acid [phthalimidoperoxyhexanoic acid (PAP)], and o-carboxybenzamidoperoxycaproic acid; aliphatic and aromatic diperoxydicarboxylic acids such as diperoxydodecanedioic acid, diperoxyazelaic acid, diperoxysebacic acid, diperoxybrassylic acid, 2-decyldiperoxybutanedioic acid, and diperoxyphthalic, -isophthalic and -terephthalic acids; perimidic acids; peroxymonosulfuric acid; peroxydisulfuric acid; peroxyphosphoric acid; peroxysilicic acid; and mixtures of said compounds.

ATC or a short chain triglyceride like triacetin has the advantage that they are environmentally friendly. Furthermore, acetyl triethyl citrate and triacetin have good hydrolytical stability in the product upon storage and are efficient bleach activators. Finally, ATC is multifunctional, as the citrate released in the perhydrolysis reaction may function as a builder.

In another embodiment, the present invention relates to a polypeptide having hexosaminidase activity encoded by a polynucleotide having a sequence identity to the mature polypeptide coding sequence of SEQ ID NO 12 of at least 60%, e.g., at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100%. In a further embodiment, the polypeptide has been isolated.

In another embodiment, the present invention relates to a polypeptide having hexosaminidase activity encoded by a polynucleotide having a sequence identity to the mature polypeptide coding sequence of SEQ ID NO 14 of at least 60%, e.g., at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100%. In a further embodiment, the polypeptide has been isolated.

In another embodiment, the present invention relates to variants of the mature polypeptide of SEQ ID NO 2, SEQ ID NO 4, SEQ ID NO 6, SEQ ID NO 13 or SEQ ID NO 15 comprising a substitution, deletion, and/or insertion at one or more (e.g., several) positions. In an embodiment, the number of amino acid substitutions, deletions and/or insertions introduced into the mature polypeptide of SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9, SEQ ID NO 10 or SEQ ID NO 11 is up to 10, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. The amino acid changes may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-30 amino acids; small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain. Examples of conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine and valine), aromatic amino acids (phenylalanine, tryptophan and tyrosine), and small amino acids (glycine, alanine, serine, threonine and methionine). Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile, Leu/Val, Ala/Glu, and Asp/Gly.

Alternatively, the amino acid changes are of such a nature that the physico-chemical properties of the polypeptides are altered. For example, amino acid changes may improve the thermal stability of the polypeptide, alter the substrate specificity, change the pH optimum, and the like. Essential amino acids in a polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant molecules are tested for hexosaminidase activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide. The polypeptides of the invention are hexosaminidase e.g. dispersins belonging to the Terribacillus clade. Terribacillus dispersins are β-hexosaminidases that specifically hydrolyzes β-1,6-glycosidic linkages of N-acetylglucosamine polymers, which may be found e.g. in biofilm. Dispersin B which belongs to a different clade than the polypeptides (hexosaminidases) of the invention contains three highly conserved acidic residues: an aspartic acid at residue 183 (D183), a glutamic acid at residue 184 (E184), and a glutamic acid at residue 332 (E332). Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA 86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can be used include error-prone PCR, phage Dsplay (e.g., Lowman et al., 1991, Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204), and region-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Ner et al., 1988, DNA 7: 127). Mutagenesis/shuffling methods can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides expressed by host cells (Ness et al., 1999, Nature Biotechnology 17: 893-896). Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using standard methods in the art. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide. The polypeptide may be a hybrid polypeptide in which a region of one polypeptide is fused at the N-terminus or the C-terminus of a region of another polypeptide.

The polypeptide may be a fusion polypeptide or cleavable fusion polypeptide in which another polypeptide is fused at the N-terminus or the C-terminus of the polypeptide of the present invention. A fusion polypeptide is produced by fusing a polynucleotide encoding another polypeptide to a polynucleotide of the present invention. Techniques for producing fusion polypeptides are known in the art, and include ligating the coding sequences encoding the polypeptides so that they are in frame and that expression of the fusion polypeptide is under control of the same promoter(s) and terminator. Fusion polypeptides may also be constructed using intein technology in which fusion polypeptides are created post-translationally (Cooper et al., 1993, EMBO J. 12: 2575-2583; Dawson et al., 1994, Science 266: 776-779). A fusion polypeptide can further comprise a cleavage site between the two polypeptides. Upon secretion of the fusion protein, the site is cleaved releasing the two polypeptides. Examples of cleavage sites include, but are not limited to, the sites disclosed in Martin et al., 2003, J. Ind. Microbiol. Biotechnol. 3: 568-576; Svetina et al., 2000, J. Biotechnol. 76: 245-251; Rasmussen-Wilson et al., 1997, Appl. Environ. Microbiol. 63: 3488-3493; Ward et al., 1995, Biotechnology 13: 498-503; and Contreras et al., 1991, Biotechnology 9: 378-381; Eaton et al., 1986, Biochemistry 25: 505-512; Collins-Racie et al., 1995, Biotechnology 13: 982-987; Carter et al., 1989, Proteins: Structure, Function, and Genetics 6: 240-248; and Stevens, 2003, Drug Discovery World 4: 35-48.

Sources of Polypeptides Having Hexosaminidase Activity

A polypeptide having hexosaminidase activity of the present invention may be obtained from microorganisms of any genus. For purposes of the present invention, the term “obtained from” as used herein in connection with a given source shall mean that the polypeptide encoded by a polynucleotide is produced by the source or by a strain in which the polynucleotide from the source has been inserted. In one aspect, the polypeptide obtained from a given source is secreted extracellularly.

In another aspect, the polypeptide is a Terribacillus polypeptide, e.g., a polypeptide obtained from Terribacillus saccharophilus.

It will be understood that for the aforementioned species, the invention encompasses both the perfect and imperfect states, and other taxonomic equivalents, e.g., anamorphs, regardless of the species name by which they are known. Those skilled in the art will readily recognize the identity of appropriate equivalents.

Strains of these species are readily accessible to the public in a number of culture collections, such as the American Type Culture Collection (ATCC), Deutsche Sammlung von Mikroorganismen and Zellkulturen GmbH (DSMZ), Centraalbureau Voor Schimmelcultures (CBS), and Agricultural Research Service Patent Culture Collection, Northern Regional Research Center (NRRL).

The polypeptide may be identified and obtained from other sources including microorganisms isolated from nature (e.g., soil, composts, water, etc.) or DNA samples obtained directly from natural materials (e.g., soil, composts, water, etc.) using the above-mentioned probes. Techniques for isolating microorganisms and DNA directly from natural habitats are well known in the art. A polynucleotide encoding the polypeptide may then be obtained by similarly screening a genomic DNA or cDNA library of another microorganism or mixed DNA sample. Once a polynucleotide encoding a polypeptide has been detected with the probe(s), the polynucleotide can be isolated or cloned by utilizing techniques that are known to those of ordinary skill in the art (see, e.g., Sambrook et al., 1989, supra).

Nucleic Acid Constructs

The present invention also relates to nucleic acid constructs comprising a polynucleotide of the present invention operably linked to one or more control sequences that direct the expression of the coding sequence in a suitable host cell under conditions compatible with the control sequences.

The polynucleotide may be manipulated in a variety of ways to provide for expression of the polypeptide. Manipulation of the polynucleotide prior to its insertion into a vector may be desirable or necessary depending on the expression vector. The techniques for modifying polynucleotides utilizing recombinant DNA methods are well known in the art.

The control sequence may be a promoter, a polynucleotide that is recognized by a host cell for expression of a polynucleotide encoding a polypeptide of the present invention. The promoter contains transcriptional control sequences that mediate the expression of the polypeptide. The promoter may be any polynucleotide that shows transcriptional activity in the host cell including variant, truncated, and hybrid promoters, and may be obtained from genes encoding extracellular or intracellular polypeptides either homologous or heterologous to the host cell.

Examples of suitable promoters for directing transcription of the nucleic acid constructs of the present invention in a bacterial host cell are the promoters obtained from the Bacillus amyloliquefaciens alpha-amylase gene (amyQ), Bacillus licheniformis alpha-amylase gene (amyL), Bacillus licheniformis penicillinase gene (penP), Bacillus stearothermophilus maltogenic amylase gene (amyM), Bacillus subtilis levansucrase gene (sacB), Bacillus subtilis xylA and xylB genes, Bacillus thuringiensis cryIIIA gene (Agaisse and Lereclus, 1994, Molecular Microbiology 13: 97-107), E. coli lac operon, E. coli trc promoter (Egon et al., 1988, Gene 69: 301-315), Streptomyces coelicolor agarase gene (dagA), and prokaryotic beta-lactamase gene (Villa-Kamaroff et al., 1978, Proc. Natl. Acad. Sci. USA 75: 3727-3731), as well as the tac promoter (DeBoer et al., 1983, Proc. Natl. Acad. Sci. USA 80: 21-25). Further promoters are described in “Useful proteins from recombinant bacteria” in Gilbert et al., 1980, Scientific American 242: 74-94; and in Sambrook et al., 1989, supra. Examples of tandem promoters are disclosed in WO 99/43835.

Examples of suitable promoters for directing transcription of the nucleic acid constructs of the present invention in a filamentous fungal host cell are promoters obtained from the genes for Aspergillus nidulans acetamidase, Aspergillus niger neutral alpha-amylase, Aspergillus niger acid stable alpha-amylase, Aspergillus niger or Aspergillus awamori glucoamylase (glaA), Aspergillus oryzae TAKA amylase, Aspergillus oryzae alkaline protease, Aspergillus oryzae triose phosphate isomerase, Fusarium oxysporum trypsin-like protease (WO 96/00787), Fusarium venenatum amyloglucosidase (WO 00/56900), Fusarium venenatum Daria (WO 00/56900), Fusarium venenatum Quinn (WO 00/56900), Rhizomucor miehei lipase, Rhizomucor miehei aspartic proteinase, Trichoderma reesei beta-glucosidase, Trichoderma reesei cellobiohydrolase I, Trichoderma reesei cellobiohydrolase II, Trichoderma reesei endoglucanase I, Trichoderma reesei endoglucanase II, Trichoderma reesei endoglucanase III, Trichoderma reesei endoglucanase V, Trichoderma reesei xylanase I, Trichoderma reesei xylanase II, Trichoderma reesei xylanase III, Trichoderma reesei beta-xylosidase, and Trichoderma reesei translation elongation factor, as well as the NA2-tpi promoter (a modified promoter from an Aspergillus neutral alpha-amylase gene in which the untranslated leader has been replaced by an untranslated leader from an Aspergillus triose phosphate isomerase gene; non-limiting examples include modified promoters from an Aspergillus niger neutral alpha-amylase gene in which the untranslated leader has been replaced by an untranslated leader from an Aspergillus nidulans or Aspergillus oryzae triose phosphate isomerase gene); and variant, truncated, and hybrid promoters thereof. Other promoters are described in U.S. Pat. No. 6,011,147.

In a yeast host, useful promoters are obtained from the genes for Saccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae galactokinase (GAL1), Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH1, ADH2/GAP), Saccharomyces cerevisiae triose phosphate isomerase (TPI), Saccharomyces cerevisiae metallothionein (CUP1), and Saccharomyces cerevisiae 3-phosphoglycerate kinase. Other useful promoters for yeast host cells are described by Romanos et al., 1992, Yeast 8: 423-488.

The control sequence may also be a transcription terminator, which is recognized by a host cell to terminate transcription. The terminator is operably linked to the 3′-terminus of the polynucleotide encoding the polypeptide. Any terminator that is functional in the host cell may be used in the present invention.

Preferred terminators for bacterial host cells are obtained from the genes for Bacillus clausii alkaline protease (aprH), Bacillus licheniformis alpha-amylase (amyL), and Escherichia coli ribosomal RNA (rrnB).

Preferred terminators for filamentous fungal host cells are obtained from the genes for Aspergillus nidulans acetamidase, Aspergillus nidulans anthranilate synthase, Aspergillus niger glucoamylase, Aspergillus niger alpha-glucosidase, Aspergillus oryzae TAKA amylase, Fusarium oxysporum trypsin-like protease, Trichoderma reesei beta-glucosidase, Trichoderma reesei cellobiohydrolase I, Trichoderma reesei cellobiohydrolase II, Trichoderma reesei endoglucanase I, Trichoderma reesei endoglucanase II, Trichoderma reesei endoglucanase III, Trichoderma reesei endoglucanase V, Trichoderma reesei xylanase I, Trichoderma reesei xylanase II, Trichoderma reesei xylanase III, Trichoderma reesei beta-xylosidase, and Trichoderma reesei translation elongation factor. Preferred terminators for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase, Saccharomyces cerevisiae cytochrome C (CYC1), and Saccharomyces cerevisiae glyceraldehyde-3-phosphate dehydrogenase. Other useful terminators for yeast host cells are described by Romanos et al., 1992, supra. The control sequence may also be an mRNA stabilizer region downstream of a promoter and upstream of the coding sequence of a gene which increases expression of the gene. Examples of suitable mRNA stabilizer regions are obtained from a Bacillus thuringiensis cryIIIA gene (WO 94/25612) and a Bacillus subtilis SP82 gene (Hue et al., 1995, Journal of Bacteriology 177: 3465-3471). The control sequence may also be a leader, a nontranslated region of an mRNA that is important for translation by the host cell. The leader is operably linked to the 5′-terminus of the polynucleotide encoding the polypeptide. Any leader that is functional in the host cell may be used. Preferred leaders for filamentous fungal host cells are obtained from the genes for Aspergillus oryzae TAKA amylase and Aspergillus nidulans triose phosphate isomerase. Suitable leaders for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae 3-phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, and Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH2/GAP). The control sequence may also be a polyadenylation sequence, a sequence operably linked to the 3′-terminus of the polynucleotide and, when transcribed, is recognized by the host cell as a signal to add polyadenosine residues to transcribed mRNA. Any polyadenylation sequence that is functional in the host cell may be used. Preferred polyadenylation sequences for filamentous fungal host cells are obtained from the genes for Aspergillus nidulans anthranilate synthase, Aspergillus niger glucoamylase, Aspergillus niger alpha-glucosidase Aspergillus oryzae TAKA amylase, and Fusarium oxysporum trypsin-like protease. Useful polyadenylation sequences for yeast host cells are described by Guo and Sherman, 1995, Mol. Cellular Biol. 15: 5983-5990.

The control sequence may also be a signal peptide coding region that encodes a signal peptide linked to the N-terminus of a polypeptide and directs the polypeptide into the cell's secretory pathway. The 5′-end of the coding sequence of the polynucleotide may inherently contain a signal peptide coding sequence naturally linked in translation reading frame with the segment of the coding sequence that encodes the polypeptide. Alternatively, the 5′-end of the coding sequence may contain a signal peptide coding sequence that is foreign to the coding sequence. A foreign signal peptide coding sequence may be required where the coding sequence does not naturally contain a signal peptide coding sequence. Alternatively, a foreign signal peptide coding sequence may simply replace the natural signal peptide coding sequence in order to enhance secretion of the polypeptide. However, any signal peptide coding sequence that directs the expressed polypeptide into the secretory pathway of a host cell may be used.

Effective signal peptide coding sequences for bacterial host cells are the signal peptide coding sequences obtained from the genes for Bacillus NCI B 11837 maltogenic amylase, Bacillus licheniformis subtilisin, Bacillus licheniformis beta-lactamase, Bacillus stearothermophilus alpha-amylase, Bacillus stearothermophilus neutral proteases (nprT, nprS, nprM), and Bacillus subtilis prsA. Further signal peptides are described by Simonen and Palva, 1993, Microbiological Reviews 57: 109-137. Effective signal peptide coding sequences for filamentous fungal host cells are the signal peptide coding sequences obtained from the genes for Aspergillus niger neutral amylase, Aspergillus niger glucoamylase, Aspergillus oryzae TAKA amylase, Humicola insolens cellulase, Humicola insolens endoglucanase V, Humicola lanuginosa lipase, and Rhizomucor miehei aspartic proteinase. Useful signal peptides for yeast host cells are obtained from the genes for Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiae invertase. Other useful signal peptide coding sequences are described by Romanos et al., 1992, supra.

The control sequence may also be a propeptide coding sequence that encodes a propeptide positioned at the N-terminus of a polypeptide. The resultant polypeptide is known as a proenzyme or propolypeptide (or a zymogen in some cases). A propolypeptide is generally inactive and can be converted to an active polypeptide by catalytic or autocatalytic cleavage of the propeptide from the propolypeptide. The propeptide coding sequence may be obtained from the genes for Bacillus subtilis alkaline protease (aprE), Bacillus subtilis neutral protease (nprT), Myceliophthora thermophila laccase (WO 95/33836), Rhizomucor miehei aspartic proteinase, and Saccharomyces cerevisiae alpha-factor.

Where both signal peptide and propeptide sequences are present, the propeptide sequence is positioned next to the N-terminus of a polypeptide and the signal peptide sequence is positioned next to the N-terminus of the propeptide sequence.

It may also be desirable to add regulatory sequences that regulate expression of the polypeptide relative to the growth of the host cell. Examples of regulatory sequences are those that cause expression of the gene to be turned on or off in response to a chemical or physical stimulus, including the presence of a regulatory compound. Regulatory sequences in prokaryotic systems include the lac, tac, and trp operator systems. In yeast, the ADH2 system or GAL1 system may be used. In filamentous fungi, the Aspergillus niger glucoamylase promoter, Aspergillus oryzae TAKA alpha-amylase promoter, and Aspergillus oryzae glucoamylase promoter, Trichoderma reesei cellobiohydrolase I promoter, and Trichoderma reesei cellobiohydrolase II promoter may be used. Other examples of regulatory sequences are those that allow for gene amplification. In eukaryotic systems, these regulatory sequences include the dihydrofolate reductase gene that is amplified in the presence of methotrexate, and the metallothionein genes that are amplified with heavy metals. In these cases, the polynucleotide encoding the polypeptide would be operably linked to the regulatory sequence.

Expression Vectors

The present invention also relates to recombinant expression vectors comprising a polynucleotide of the present invention, a promoter, and transcriptional and translational stop signals. The various nucleotide and control sequences may be joined together to produce a recombinant expression vector that may include one or more convenient restriction sites to allow for insertion or substitution of the polynucleotide encoding the polypeptide at such sites. Alternatively, the polynucleotide may be expressed by inserting the polynucleotide or a nucleic acid construct comprising the polynucleotide into an appropriate vector for expression. In creating the expression vector, the coding sequence is located in the vector so that the coding sequence is operably linked with the appropriate control sequences for expression.

The recombinant expression vector may be any vector (e.g., a plasmid or virus) that can be conveniently subjected to recombinant DNA procedures and can bring about expression of the polynucleotide. The choice of the vector will typically depend on the compatibility of the vector with the host cell into which the vector is to be introduced. The vector may be a linear or closed circular plasmid.

The vector may be an autonomously replicating vector, i.e., a vector that exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g., a plasmid, an extrachromosomal element, a minichromosome, or an artificial chromosome. The vector may contain any means for assuring self-replication. Alternatively, the vector may be one that, when introduced into the host cell, is integrated into the genome and replicated together with the chromosome(s) into which it has been integrated. Furthermore, a single vector or plasmid or two or more vectors or plasmids that together contain the total DNA to be introduced into the genome of the host cell, or a transposon, may be used.

The vector preferably contains one or more selectable markers that permit easy selection of transformed, transfected, transduced, or the like cells. A selectable marker is a gene the product of which provides for biocide or viral resistance, resistance to heavy metals, prototrophy to auxotrophs, and the like.

Examples of bacterial selectable markers are Bacillus licheniformis or Bacillus subtilis dal genes, or markers that confer antibiotic resistance such as ampicillin, chloramphenicol, kanamycin, neomycin, spectinomycin, or tetracycline resistance. Suitable markers for yeast host cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2, MET3, TRP1, and URA3. Selectable markers for use in a filamentous fungal host cell include, but are not limited to, adeA (phosphoribosylaminoimidazole-succinocarboxamide synthase), adeB (phosphoribosylaminoimidazole synthase), amdS (acetamidase), argB (ornithine carbamoyltransferase), bar (phosphinothricin acetyltransferase), hph (hygromycin phosphotransferase), niaD (nitrate reductase), pyrG (orotidine-5′-phosphate decarboxylase), sC (sulfate adenyltransferase), and trpC (anthranilate synthase), as well as equivalents thereof. Preferred for use in an Aspergillus cell are Aspergillus nidulans or Aspergillus oryzae amdS and pyrG genes and a Streptomyces hygroscopicus bar gene. Preferred for use in a Trichoderma cell are adeA, adeB, amdS, hph, and pyrG genes.

The selectable marker may be a dual selectable marker system as described in WO 2010/039889. In one aspect, the dual selectable marker is an hph-tk dual selectable marker system.

The vector preferably contains an element(s) that permits integration of the vector into the host cell's genome or autonomous replication of the vector in the cell independent of the genome.

For integration into the host cell genome, the vector may rely on the polynucleotide's sequence encoding the polypeptide or any other element of the vector for integration into the genome by homologous or non-homologous recombination. Alternatively, the vector may contain additional polynucleotides for directing integration by homologous recombination into the genome of the host cell at a precise location(s) in the chromosome(s). To increase the likelihood of integration at a precise location, the integrational elements should contain a sufficient number of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000 base pairs, and 800 to 10,000 base pairs, which have a high degree of sequence identity to the corresponding target sequence to enhance the probability of homologous recombination. The integrational elements may be any sequence that is homologous with the target sequence in the genome of the host cell. Furthermore, the integrational elements may be non-encoding or encoding polynucleotides. On the other hand, the vector may be integrated into the genome of the host cell by non-homologous recombination.

For autonomous replication, the vector may further comprise an origin of replication enabling the vector to replicate autonomously in the host cell in question. The origin of replication may be any plasmid replicator mediating autonomous replication that functions in a cell. The term “origin of replication” or “plasmid replicator” means a polynucleotide that enables a plasmid or vector to replicate in vivo.

Examples of bacterial origins of replication are the origins of replication of plasmids pBR322, pUC19, pACYC177, and pACYC184 permitting replication in E. coli, and pUB110, pE194, pTA1060, and pAMβ1 permitting replication in Bacillus.

Examples of origins of replication for use in a yeast host cell are the 2 micron origin of replication, ARS1, ARS4, the combination of ARS1 and CEN3, and the combination of ARS4 and CEN6.

Examples of origins of replication useful in a filamentous fungal cell are AMA1 and ANSI (Gems et al., 1991, Gene 98: 61-67; Cullen et al., 1987, Nucleic Acids Res. 15: 9163-9175; WO 00/24883). Isolation of the AMA1 gene and construction of plasmids or vectors comprising the gene can be accomplished according to the methods disclosed in WO 00/24883.

More than one copy of a polynucleotide of the present invention may be inserted into a host cell to increase production of a polypeptide. An increase in the copy number of the polynucleotide can be obtained by integrating at least one additional copy of the sequence into the host cell genome or by including an amplifiable selectable marker gene with the polynucleotide where cells containing amplified copies of the selectable marker gene, and thereby additional copies of the polynucleotide, can be selected for by cultivating the cells in the presence of the appropriate selectable agent.

The procedures used to ligate the elements described above to construct the recombinant expression vectors of the present invention are well known to one skilled in the art (see, e.g., Sambrook et al., 1989, supra).

Host Cells

The present invention also relates to recombinant host cells, comprising a polynucleotide of the present invention operably linked to one or more control sequences that direct the production of a polypeptide of the present invention. A construct or vector comprising a polynucleotide is introduced into a host cell so that the construct or vector is maintained as a chromosomal integrant or as a self-replicating extra-chromosomal vector as described earlier. The term “host cell” encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication. The choice of a host cell will to a large extent depend upon the gene encoding the polypeptide and its source.

The host cell may be any cell useful in the recombinant production of a polypeptide of the present invention, e.g., a prokaryote or a eukaryote.

The prokaryotic host cell may be any Gram-positive or Gram-negative bacterium. Gram-positive bacteria include, but are not limited to, Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus, Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus, and Streptomyces. Gram-negative bacteria include, but are not limited to, Campylobacter, E. coli, Flavobacterium, Fusobacterium, Helicobacter, Ilyobacter, Neisseria, Pseudomonas, Salmonella, and Ureaplasma.

The bacterial host cell may be any Bacillus cell including, but not limited to, Bacillus alkalophilus, Bacillus altitudinis, Bacillus amyloliquefaciens, B. amyloliquefaciens subsp. plantarum, Bacillus brevis, Bacillus circulans, Bacillus clausii, Bacillus coagulans, Bacillus firmus, Bacillus lautus, Bacillus lentus, Bacillus licheniformis, Bacillus megaterium, Bacillus methylotrophicus, Bacillus pumilus, Bacillus safensis, Bacillus stearothermophilus, Bacillus subtilis, and Bacillus thuringiensis cells.

The bacterial host cell may also be any Streptococcus cell including, but not limited to, Streptococcus equisimilis, Streptococcus pyogenes, Streptococcus uberis, and Streptococcus equi subsp. Zooepidemicus cells.

The bacterial host cell may also be any Streptomyces cell including, but not limited to, Streptomyces achromogenes, Streptomyces avermitilis, Streptomyces coelicolor, Streptomyces griseus, and Streptomyces lividans cells.

The introduction of DNA into a Bacillus cell may be effected by protoplast transformation (see, e.g., Chang and Cohen, 1979, Mol. Gen. Genet. 168: 111-115), competent cell transformation (see, e.g., Young and Spizizen, 1961, J. Bacteriol. 81: 823-829, or Dubnau and Davidoff-Abelson, 1971, J. Mol. Biol. 56: 209-221), electroporation (see, e.g., Shigekawa and Dower, 1988, Biotechniques 6: 742-751), or conjugation (see, e.g., Koehler and Thorne, 1987, J. Bacteriol. 169: 5271-5278). The introduction of DNA into an E. coli cell may be effected by protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol. 166: 557-580) or electroporation (see, e.g., Dower et al., 1988, Nucleic Acids Res. 16: 6127-6145). The introduction of DNA into a Streptomyces cell may be effected by protoplast transformation, electroporation (see, e.g., Gong et al., 2004, Folia Microbiol. (Praha) 49: 399-405), conjugation (see, e.g., Mazodier et al., 1989, J. Bacteriol. 171: 3583-3585), or transduction (see, e.g., Burke et al., 2001, Proc. Natl. Acad. Sci. USA 98: 6289-6294). The introduction of DNA into a Pseudomonas cell may be effected by electroporation (see, e.g., Choi et al., 2006, J. Microbiol. Methods 64: 391-397) or conjugation (see, e.g., Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71: 51-57). The introduction of DNA into a Streptococcus cell may be effected by natural competence (see, e.g., Perry and Kuramitsu, 1981, Infect.

The host cell may also be a eukaryote, such as a mammalian, insect, plant, or fungal cell.

The host cell may be a fungal cell. “Fungi” as used herein includes the phyla Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota as well as the Oomycota and all mitosporic fungi (as defined by Hawksworth et al., In, Ainsworth and Bisby's Dictionary of The Fungi, 8th edition, 1995, CAB International, University Press, Cambridge, UK).

The fungal host cell may be a yeast cell. “Yeast” as used herein includes ascosporogenous yeast (Endomycetales), basidiosporogenous yeast, and yeast belonging to the Fungi Imperfecti (Blastomycetes). Since the classification of yeast may change in the future, for the purposes of this invention, yeast shall be defined as described in Biology and Activities of Yeast (Skinner, Passmore, and Davenport, editors, Soc. App. Bacteriol. Symposium Series No. 9, 1980).

The yeast host cell may be a Candida, Hansenula, Kluyveromyces, Pichia, Saccharomyces, Schizosaccharomyces, or Yarrowia cell, such as a Kluyveromyces lactis, Saccharomyces carlsbergensis, Saccharomyces cerevisiae, Saccharomyces diastaticus, Saccharomyces douglasii, Saccharomyces kluyveri, Saccharomyces norbensis, Saccharomyces oviformis, or Yarrowia lipolytica cell.

The fungal host cell may be a filamentous fungal cell. “Filamentous fungi” include all filamentous forms of the subdivision Eumycota and Oomycota (as defined by Hawksworth et al., 1995, supra). The filamentous fungi are generally characterized by a mycelial wall composed of chitin, cellulose, glucan, chitosan, mannan, and other complex polysaccharides. Vegetative growth is by hyphal elongation and carbon catabolism is obligately aerobic. In contrast, vegetative growth by yeasts such as Saccharomyces cerevisiae is by budding of a unicellular thallus and carbon catabolism may be fermentative.

The filamentous fungal host cell may be an Acremonium, Aspergillus, Aureobasidium, Bjerkandera, Ceriporiopsis, Chrysosporium, Coprinus, Coriolus, Cryptococcus, Filibasidium, Fusarium, Humicola, Magnaporthe, Mucor, Myceliophthora, Neocallimastix, Neurospora, Paecilomyces, Penicillium, Phanerochaete, Phiebia, Piromyces, Pleurotus, Schizophyllum, Talaromyces, Thermoascus, Thielavia, Tolypocladium, Trametes, or Trichoderma cell.

Fungal cells may be transformed by a process involving protoplast formation, transformation of the protoplasts, and regeneration of the cell wall in a manner known per se. Suitable procedures for transformation of Aspergillus and Trichoderma host cells are described in EP 238023, Yelton et al., 1984, Proc. Natl. Acad. Sci. USA 81: 1470-1474, and Christensen et al., 1988, Bio/Technology 6: 1419-1422. Suitable methods for transforming Fusarium species are described by Malardier et al., 1989, Gene 78: 147-156, and WO 96/00787. Yeast may be transformed using the procedures described by Becker and Guarente, In Abelson, J. N. and Simon, M.

Bacteriol. 153: 163; and Hinnen et al., 1978, Proc. Natl. Acad. Sci. USA 75: 1920.

Methods of Production

The present invention also relates to methods of producing a polypeptide of the present invention, comprising (a) cultivating a cell, which in its wild-type form produces the polypeptide, under conditions conducive for production of the polypeptide; and optionally, (b) recovering the polypeptide. In one aspect, the cell is a Terribacillus cell. In another aspect, the cell is a Terribacillus saccharophilus cell. In one aspect, the cell is a Terribacillus cell. In another aspect, the cell is a Terribacillus goriensis cell.

The present invention also relates to methods of producing a polypeptide of the present invention, comprising (a) cultivating a recombinant host cell of the present invention under conditions conducive for production of the polypeptide; and optionally, (b) recovering the polypeptide.

The host cells are cultivated in a nutrient medium suitable for production of the polypeptide using methods known in the art. For example, the cells may be cultivated by shake flask cultivation, or small-scale or large-scale fermentation (including continuous, batch, fed-batch, or solid state fermentations) in laboratory or industrial fermentors in a suitable medium and under conditions allowing the polypeptide to be expressed and/or isolated. The cultivation takes place in a suitable nutrient medium comprising carbon and nitrogen sources and inorganic salts, using procedures known in the art. Suitable media are available from commercial suppliers or may be prepared according to published compositions (e.g., in catalogues of the American Type Culture Collection). If the polypeptide is secreted into the nutrient medium, the polypeptide can be recovered directly from the medium. If the polypeptide is not secreted, it can be recovered from cell lysates.

The polypeptide may be detected using methods known in the art that are specific for the polypeptides having hexosaminidase activity. These detection methods include, but are not limited to, use of specific antibodies, formation of an enzyme product, or disappearance of an enzyme substrate. For example, an enzyme assay may be used to determine the activity of the polypeptide.

The polypeptide may be recovered using methods known in the art. For example, the polypeptide may be recovered from the nutrient medium by conventional procedures including, but not limited to, collection, centrifugation, filtration, extraction, spray-drying, evaporation, or precipitation. In one aspect, a fermentation broth comprising the polypeptide is recovered.

The polypeptide may be purified by a variety of procedures known in the art including, but not limited to, chromatography (e.g., ion exchange, affinity, hydrophobic, chromatofocusing, and size exclusion), electrophoretic procedures (e.g., preparative isoelectric focusing), differential solubility (e.g., ammonium sulfate precipitation), SDS-PAGE, or extraction (see, e.g., Protein Purification, Janson and Ryden, editors, VCH Publishers, New York, 1989) to obtain substantially pure polypeptides.

In an alternative aspect, the polypeptide is not recovered, but rather a host cell of the present invention expressing the polypeptide is used as a source of the polypeptide.

Formulation of Detergent Products

The cleaning composition may be in any convenient form, e.g., a bar, a homogenous tablet, a tablet having two or more layers, a pouch having one or more compartments, a regular or compact powder, a granule, a paste, a gel, or a regular, compact or concentrated liquid. Pouches can be configured as single or multicompartments. It can be of any form, shape and material which is suitable for hold the composition, e.g. without allowing the release of the composition to release of the composition from the pouch prior to water contact. The pouch is made from water soluble film which encloses an inner volume. Said inner volume can be divided into compartments of the pouch. Preferred films are polymeric materials preferably polymers which are formed into a film or sheet. Preferred polymers, copolymers or derivates thereof are selected polyacrylates, and water soluble acrylate copolymers, methyl cellulose, carboxy methyl cellulose, sodium dextrin, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, malto dextrin, poly methacrylates, most preferably polyvinyl alcohol copolymers and, hydroxypropyl methyl cellulose (HPMC). Preferably the level of polymer in the film for example PVA is at least about 60%. Preferred average molecular weight will typically be about 20,000 to about 150,000. Films can also be of blended compositions comprising hydrolytically degradable and water soluble polymer blends such as polylactide and polyvinyl alcohol (known under the Trade reference M8630 as sold by MonoSol LLC, Indiana, USA) plus plasticisers like glycerol, ethylene glycerol, propylene glycol, sorbitol and mixtures thereof. The pouches can comprise a solid laundry cleaning composition or part components and/or a liquid cleaning composition or part components separated by the water soluble film. The compartment for liquid components can be different in composition than compartments containing solids: US2009/0011970 A1.

Detergent ingredients can be separated physically from each other by compartments in water dissolvable pouches or in different layers of tablets. Thereby negative storage interaction between components can be avoided. Different dissolution profiles of each of the compartments can also give rise to delayed dissolution of selected components in the wash solution.

A liquid or gel detergent, which is not unit dosed, may be aqueous, typically containing at least 20% by weight and up to 95% water, such as up to about 70% water, up to about 65% water, up to about 55% water, up to about 45% water, up to about 35% water. Other types of liquids, including without limitation, alkanols, amines, diols, ethers and polyols may be included in an aqueous liquid or gel. An aqueous liquid or gel detergent may contain from 0-30% organic solvent.

A liquid or gel detergent may be non-aqueous.

Laundry Soap Bars

The polypeptides of the invention may be added to laundry soap bars and used for hand washing laundry, fabrics and/or textiles. The term laundry soap bar includes laundry bars, soap bars, combo bars, syndet bars and detergent bars. The types of bar usually differ in the type of surfactant they contain, and the term laundry soap bar includes those containing soaps from fatty acids and/or synthetic soaps. The laundry soap bar has a physical form which is solid and not a liquid, gel or a powder at room temperature. The term solid is defined as a physical form which does not significantly change over time, i.e. if a solid object (e.g. laundry soap bar) is placed inside a container, the solid object does not change to fill the container it is placed in. The bar is a solid typically in bar form but can be in other solid shapes such as round or oval. The laundry soap bar may contain one or more additional enzymes, protease inhibitors such as peptide aldehydes (or hydrosulfite adduct or hemiacetal adduct), boric acid, borate, borax and/or phenylboronic acid derivatives such as 4-formylphenylboronic acid, one or more soaps or synthetic surfactants, polyols such as glycerine, pH controlling compounds such as fatty acids, citric acid, acetic acid and/or formic acid, and/or a salt of a monovalent cation and an organic anion wherein the monovalent cation may be for example Na⁺, K⁺ or NH₄ ⁺ and the organic anion may be for example formate, acetate, citrate or lactate such that the salt of a monovalent cation and an organic anion may be, for example, sodium formate. The laundry soap bar may also contain complexing agents like EDTA and HEDP, perfumes and/or different type of fillers, surfactants e.g. anionic synthetic surfactants, builders, polymeric soil release agents, detergent chelators, stabilizing agents, fillers, dyes, colorants, dye transfer inhibitors, alkoxylated polycarbonates, suds suppressers, structurants, binders, leaching agents, bleaching activators, clay soil removal agents, anti-redeposition agents, polymeric dispersing agents, brighteners, fabric softeners, perfumes and/or other compounds known in the art. The laundry soap bar may be processed in conventional laundry soap bar making equipment such as but not limited to: mixers, plodders, e.g a two stage vacuum plodder, extruders, cutters, logo-stampers, cooling tunnels and wrappers. The invention is not limited to preparing the laundry soap bars by any single method. The premix may be added to the soap at different stages of the process. For example, the premix containing a soap, hexosaminidase, optionally one or more additional enzymes, a protease inhibitor, and a salt of a monovalent cation and an organic anion may be prepared and the mixture is then plodded. The hexosaminidase and optional additional enzymes may be added at the same time as the protease inhibitor for example in liquid form. Besides the mixing step and the plodding step, the process may further comprise the steps of milling, extruding, cutting, stamping, cooling and/or wrapping.

Formulation of Enzyme in Co-Granule

The polypeptides of the invention may be formulated as a granule for example as a co-granule that combines one or more enzymes. Each enzyme will then be present in more granules securing a more uniform distribution of enzymes in the detergent. This also reduces the physical segregation of different enzymes due to different particle sizes. Methods for producing multi-enzyme co-granulates for the detergent industry are disclosed in the IP.com disclosure IPCOM000200739D. Another example of formulation of enzymes using co-granulates are disclosed in WO 2013/188331, which relates to a detergent composition comprising (a) a multi-enzyme co-granule; (b) less than 10 wt zeolite (anhydrous basis); and (c) less than 10 wt phosphate salt (anhydrous basis), wherein said enzyme co-granule comprises from 10 to 98 wt % moisture sink components and the composition additionally comprises from 20 to 80 wt % detergent moisture sink components. The multi-enzyme co-granule may comprise a hexosaminidase and one or more enzymes selected from the group consisting of lipases, cellulases, xyloglucanases, perhydrolases, peroxidases, lipoxygenases, laccases, hemicellulases, proteases, cellobiose dehydrogenases, xylanases, phospho lipases, esterases, cutinases, pectinases, mannanases, pectate lyases, keratinases, reductases, oxidases, phenoloxidases, ligninases, pullulanases, tannases, pentosanases, lichenases glucanases, arabinosidases, hyaluronidase, chondroitinase, amylases, and mixtures thereof.

Wash Assays Mini Launder-O-Meter (MiniLOM) Model Wash System

MiniLOM is a mini wash system in which washes are performed in 50 ml test tubes placed in a Stuart rotator. Each tube simulates one small washing machine and during an experiment, each will contain a solution of a specific detergent/enzyme system to be tested along with the soiled and unsoiled fabrics it is tested on. Mechanical stress is achieved via rotation (typically 20 rpm), and the temperature is controlled by placement of the rotator in a heating cabinet/room.

Terg-O-toMeter (TOM) Wash Assay

The Terg-O-toMeter (TOM) is a medium scale model wash system that can be applied to test 12 different wash conditions simultaneously. A TOM is basically a large temperature controlled water bath with up to 12 open metal beakers submerged into it. Each beaker constitutes one small top loader style washing machine and during an experiment, each of them will contain a solution of a specific detergent/enzyme system and the soiled and unsoiled fabrics its performance is tested on. Mechanical stress is achieved by a rotating stirring arm, which stirs the liquid within each beaker. Because the TOM beakers have no lid, it is possible to withdraw samples during a TOM experiment and assay for information on-line during wash.

The TOM model wash system is mainly used in medium scale testing of detergents and enzymes at US or LA/AP wash conditions. In a TOM experiment, factors such as the ballast to soil ratio and the fabric to wash liquor ratio can be varied. Therefore, the TOM provides the link between small scale experiments, such as AMSA and mini-wash, and the more time consuming full scale experiments in top loader washing machines. Equipment: The water bath with 12 steel beakers and 1 rotating arm per beaker with capacity of 500 or 1200 mL of detergent solution. Temperature ranges from 5 to 80° C. The water bath must be filled up with deionised water. Rotational speed can be set up to 70 to 120 rpm/min. Set temperature in the Terg-O-toMeter and start the rotation in the water bath. Wait for the temperature to adjust (tolerance is +/−0.5° C.). All beakers shall be clean and without traces of prior test material. The wash solution with desired amount of detergent, temperature and water hardness is prepared in a bucket. The detergent is allowed to dissolve during magnet stirring for 10 min. Wash solution shall be used within 30 to 60 min after preparation. 800 ml wash solution is added into a TOM beaker. The wash solution is agitated at 120 rpm and optionally one or more enzymes are added to the beaker. The swatches are sprinkled into the beaker and then the ballast load. Time measurement starts when the swatches and ballast are added to the beaker. The swatches are washed for 20 minutes after which agitation is terminated. The wash load is subsequently transferred from the TOM beaker to a sieve and rinse with cold tap water. The soiled swatches are separated from the ballast load. The soil swatches are transferred to a 5L beaker with cold tap water under running water for 5 minutes. The ballast load is kept separately for the coming inactivation. The water is gently pressed out of the swatches by hand and placed on a tray covered with a paper. Another paper is placed on top of the swatches. The swatches are allowed to dry overnight before subjecting the swatches to analysis, such as measuring the color intensity using a Color Eye as described herein.

The present invention is further described by the following examples that should not be construed as limiting the scope of the invention.

Assays Assay 1: Hexosaminidase Activity

The hexosaminidase activity of the mature polypeptides with SEQ ID NO 7, SEQ ID NO 8, and SEQ ID NO 9, was determined using 4-nitrophenyl N-acetyl-β-D-glucosaminide (Sigma-Aldrich) as substrate. The enzymatic reaction was performed in triplicates in a 96 well flat bottom polystyrene microtiter plate (Thermo Scientific) with the following conditions: 50 mM 2-(N-morpholino) ethanesulfonic acid pH 6 buffer, 1.5 mg/ml 4-nitrophenyl N-acetyl-β-D-glucosaminide and 20 μg/ml purified enzyme sample in a total reaction volume of 100 μl. Blank samples without enzyme were run in parallel. The reactions were carried out at 37° C. in a Thermomixer comfort (Eppendorf). After 10 minutes of incubation, 5 μl 1 M NaOH was added to each reaction mixture to stop the enzymatic reaction. The absorbance was read at 405 nm using a POLARstar Omega plate reader (BMG LABTECH) to estimate the formation of 4-nitrophenolate ion released because of enzymatic hydrolysis of the 4-nitrophenyl N-acetyl-β-D-glucosaminide substrate. The results are summarized in the table below. The table shows the average absorbance measured at 405 nm for each reaction performed in triplicates. It is seen that the absorbance is higher for the reaction carried out with SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9, compared to blank without enzyme which demonstrates that SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9 exhibit hexosaminidase activity.

Assay 2: Hexosaminidase Activity

The hexosaminidase activity of the mature polypeptides with SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9, and SEQ ID NO 10, was determined using 4-Methylumbeliferyl N-acetyl-β-D-glucosaminide (Sigma-Aldrich) as substrate. The enzymatic reaction was performed in triplicates in a 96 well flat bottom polystyrene microtiter plate (Thermo Scientific) with the following conditions: 20 mM 3-morpholinopropane-1-sulfonic add pH 7 buffer, 5 mM 4-Methylumbeliferyl N-acetyl-β-D-glucosaminide and 20 nM purified enzyme sample in a total reaction volume of 200 μl. Blank samples without enzyme were run in parallel. The reactions were carried out at ambient temperature 20-25° C. The reaction kinetics was followed immediately after mixing of enzyme and substrate using a SpectraMax M2e plate reader. Excitation wavelength was set to 368 nm and fluorescence emission reading was done at 448 nm. The reaction was followed for 30 min with 60 second intervals. Increase in fluorescence signal was used to estimate the formation of 4-Methylumbeliferyl ion released because of enzymatic hydrolysis of the 4-Methylumbeliferyl N-acetyl-β-D-glucosaminide substrate. The results are summarized in the table below. The table shows the average initial rate of reaction measured as relative fluorescence units per minute (RFU/min) using excitation at 368 nm and fluorescence emission at 448 nm for each reaction performed in triplicates. It is seen that the reaction initial rate is higher for the reaction carried out with SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9, and SEQ ID NO 10 compared to blank without enzyme which demonstrates that SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9, and SEQ ID NO 10 exhibit hexosaminidase activity.

EXAMPLES Example 1 Expression and Cloning of Hexosaminidases

The DNA encoding the hexosaminidase having the polypeptide comprised in SEQ ID NO 2 was isolated from a Terribacillus saccharophilus strain obtained from ATCC in 1969 (ATCC12327). The DNA encoding the hexosaminidase having the polypeptide comprised in SEQ ID NOS 4 and 6 were isolated from a Terribacillus goriensis and a Terribacillus saccharophilus bacterial strains respectively, isolated from an environmental soil sample collected in USA. The DNA encoding the hexosaminidase having the polypeptide comprised in SEQ ID NOS 13 and 15 were isolated later from two Terribacillus saccharophilus strains, isolated from environmental samples collected in USA. Chromosomal DNA from the four Terribacillus saccharophilus strains and the Terribacillus goriensis strain was isolated by QIAamp DNA Blood Mini Kit (Qiagen, Hilden, Germany) and subjected to full genome sequencing using Illumina technology. The genome sequence was analyzed for protein sequences that have glycosyl hydrolase domains (GH20, www.cazy.org). Three GH20 genes and corresponding sequences SEQ ID NOS: 1, 3, 5, 12 and 14 were identified from Terribacillus saccharophilus and Terribacillus goriensis strains. The codon optimized synthetic DNA encoding the mature peptide sequences of the hexosaminidases were ordered from the company Geneart. The mature polypeptides are shown in SEQ ID NO 7, 8, 9 10 and 11.

Example 2: Cloning and Expression of the Hexosaminidases

The codon optimized synthetic genes encoding the mature peptide sequences of the hexosaminidases or the polypeptides having hexosaminidase activity is shown in SEQ ID NO 7, 8, 9, 10 and 11. The sequences were inserted into a Bacillus expression vector as described in WO 12/025577. Briefly, the DNA encoding the mature peptide of the hexosaminidase gene was cloned in frame to a Bacillus clausii secretion signal (BcSP; with the following amino acid sequence: MKKPLGKIVASTALLISVAFSSSIASA (SEQ ID NO 16). BcSP replaced the native secretion signal in the gene. Downstream of the BcSP sequence, an affinity tag sequence was introduced to ease the purification process (His-tag; with the following amino acid sequence: HHHHHHPR (SEQ ID NO 17) The gene that was expressed therefore comprised the BcSP sequence followed by the His-tag sequence followed by the mature wild type GH20 sequence i.e. the polypeptides with SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9, SEQ ID NO 10 and SEQ ID NO 11. The final expression plasmid (BcSP-His-tag-GH20) was transformed into a Bacillus subtilis expression host. The GH20 BcSP-fusion gene was integrated by homologous recombination into the Bacillus subtilis host cell genome upon transformation.

The gene construct was expressed under the control of a triple promoter system (as described in WO 99/43835). The gene coding for chloramphenicol acetyltransferase was used as maker (as described in (Diderichsen et al., 1993, Plasmid 30: 312-315)). Transformants were selected on LB media agar supplemented with 6 micrograms of chloramphenicol per ml. One recombinant Bacillus subtilis clone containing the GH20 expression construct was selected and was cultivated on a rotary shaking table in 500 ml baffled Erlenmeyer flasks each containing 100 ml yeast extract-based media. After 3-5 days' cultivation time at 30° C. to 37° C., the enzyme containing supernatant was harvested by centrifugation and the enzymes was purified by His-tag purification.

Example 3: His Tag Purification Method

The His-tagged GH20 hexosaminidase enzymes were purified by immobilized metal chromatography (IMAC) using Ni²⁺ as the metal ion on 5 mL HisTrap Excel columns (GE Healthcare Life Sciences). The purification took place at pH 7 and the bound proteins were eluted with imidazole. The purity of the purified enzyme was checked by SDS-PAGE and the concentration of the enzyme determined by Absorbance 280 nm after a buffer exchange in 50 mM HEPES, 100 mM NaCl pH7.0

Example 4: Biofilm Assay

Staphylococcus aureus was kindly provided by Iñigo Lasa (Valle et al., Mol Microbiol. 2003 May; 48 (4):1075-87). The strain was grown on trypticase soy agar (TSA) at 37° C. overnight. Next day, a single colony was transferred to 15 ml tripticase soy broth (TSB) and incubated 5 hours at 37° C. under shaking. The culture was diluted 1:100 in TSB+1% glucose and 100 μL of the bacterial suspension was transferred to each well of a 96-well microtiter plates (Thermo Scientific, Nunclon Delta Surface, cat #167008) and incubated 24 hours at 37° C. without shaking. Supernatant was aspirated and wells were washed with 100 μL of 0.9% sodium chloride and filled with 100 μL of either hard water or 3.3 gr/L Model detergent A containing 0 (control) or 20, 10, 5, 2.5, 1.25, 0.62, 0.31, 0.16, 0.08, 0.04, 0.02 and 0.01 μg/mL of enzyme (the mature polypeptides having SEQ ID NO 7, SEQ ID NO 8, SEQ ID NO 9, SEQ ID NO 10 and SEQ ID NO 11). After incubation at 37° C. for 1 hour, wells were washed with water and stained for 15 min with 100 μL of 0.095% crystal violet solution (SIGMA V5265). Wells were then rinsed twice with 100 μL water, dried and the plates were scanned.

The lowest concentration of each enzyme that could reduce the visible formation of S. aureus biofilm after 1 hour incubation, in the presence and absence of detergent was determined (see Table 5). All enzymes were assayed per duplicate with similar results.

Example 5: Deep-Cleaning of Hexosaminidases in Liquid Model Detergent

Staphylococcus aureus 15981 (kind gift from Iñigo Lasa (Valle et al., Mol Microbiol. 2003 May; 48 (4):1075-87) was used as model microorganism in the present example. S. aureus was restreaked on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131; Oxoid Ltd, Basingstoke, UK) and incubated for 1 day at 37° C. A single colony was inoculated into 10 mL of TSB and the culture was incubated for 16 hours at 37° C. with shaking (200 rpm). After propagation, the S. aureus culture was diluted (1:100) in fresh TSB+1% glucose (24563; Roquette Freres) and 2 mL aliquots were added to the wells of 12-well polystyrene flat-bottom microplates (3512; Costar, Corning Incorporated, Corning, N.Y., USA), in which round swatches (diameter 2 cm) of sterile polyester (WFK30A) had been placed. Sterile TSB+1% glucose was added to control wells. After 48 h at 37° C. (static incubation), the swatches were rinsed twice with 15⁰dH water. Five rinsed swatches (sterile or with S. aureus) were placed in 50 mL test tubes and 10 mL of wash liquor (15⁰dH water with 0.2 g/L iron(III) oxide nanopowder (544884; Sigma-Aldrich) with 3.33 g/L liquid model A detergent) and 0.2 ppm enzyme (mature polypeptide with SEQ ID NO 7, 8 and 9) were added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 37° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15⁰dH water and dried on filter paper over night.

The color difference (L) values were measured using a Handheld Minolta CR-300, and are displayed in table 6. Delta values (L_((swatch washed with enzyme))−L_((swatch washed without enzyme))) are also indicated.

Example 6: Deep-Cleaning Effects of Hexosaminidases in Liquid Model Detergent

Staphylococcus aureus biofilms were grown on textile swatches (wfk30A) as described in example 5. Swatches incubated with sterile medium were included as controls. For testing the deep-cleaning properties of the hexosaminidases, five rinsed swatches (sterile or with S. aureus) were placed in 50 mL conical centrifuge tubes and 10 mL of wash liquor (15⁰dH water with 0.2 g/L iron(III) oxide nanopowder (544884; Sigma-Aldrich) with 3.33 g/L liquid model A detergent) and 0.2 ppm (or 2 ppm) enzyme was added to each tube. No enzymes were added to the controls. The test tubes were placed on a Stuart rotator and incubated for 1 hour at 37° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15⁰dH water and dried on filter paper over night.

The color difference (L) values were measured using a Handheld Minolta CR-300, and the relative wash efficiencies were calculated ((L_(With enzyme)−L_(No enzyme))/(L_(Sterile swatch)−L_(No enzyme))*100) and are indicated in table 7.

Combined with the previous examples, the results show that all the polypeptides of the invention have deep cleaning properties when compared to samples comprising no enzyme.

Example 7: Deep-Cleaning Effects of Hexosaminidases on Pseudomonas fluorescens Biofilm Swatches

A Pseudomonas fluorescens isolate from Iceland, was used as model microorganism in the present example. Pseudomonas fluorescens was restreaked on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131; Oxoid Ltd, Basingstoke, UK) and incubated for 3 days at ambient temperature. A single colony was inoculated into 10 mL of TSB and the culture was incubated for 16 hours at ambient temperature with shaking (Tetramax 1000, 460 rpm). After propagation, the culture was diluted (1:100) in fresh TSB and 1.65 mL aliquots were added to the wells of 12-well polystyrene flat-bottom microplates (3512; Costar, Corning Incorporated, Corning, N.Y., USA), in which round swatches (diameter 2 cm) of sterile textile (WFK20A) had been placed. Sterile TSB was added to control wells. After 48 h incubation at ambient temperature (statically), the swatches were rinsed twice with 0.9% (w/v) NaCl. Five rinsed swatches (sterile or with P. fluourescens biofilm) were placed in 50 mL test tubes and 10 mL of wash liquor (15⁰dH water with 0.2 g/L iron(III) oxide nanopowder (544884; Sigma-Aldrich) with 3.33 g/L liquid model A detergent) and 0.2 ppm or 2 ppm enzyme(s) was added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 30° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15⁰dH water and dried on filter paper over night.

The tristimulus light intensity (Y) values were measured using a DigiEYE colour measurement and imaging system (VeriVide) equipped with a Nikon D90 digital camera, and are displayed in table 8. Delta values (Y_((swatches washed with enzyme))−Y_((swatches washed without enzyme))) are also indicated.

Example 8 Deep-Cleaning Effects of Hexosaminidases in Liquid Model Detergent Against EPS from Different Microorganisms

Crude extracts of biofilm extracellular polymeric substances (EPS) were prepared from Staphylococcus aureus 15981 (kind gift from Iñigo Lasa (Valle, J., A. Toledo-Arana, C. Berasain, J. M. Ghigo, B. Amorena, J. R. Penades, and I. Lasa. 2003, Mol. Microbiol. 48:1075-1087), Staphylococcus cohnii (textile isolate, Denmark, 0437F4), Pseudomonas fluorescens (Isolate from Iceland) and Acinetobacter iwoffi (textile isolate from Denmark. For S. aureus, the extract was made as follows: The strain was restreaked on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131; Oxoid Ltd, Basingstoke, UK) and incubated for 3 days at 37° C. 500 mL of TSB+1% glucose (24563; Roquette Freres) was then inoculated, aliquoted into 50 ml conical centrifuge tubes (339652; Thermo Scientific Nunc) (33 ml in each), and incubated for 24 hours at 37° C. with shaking (200 rpm). The cells were subsequently pelleted by centrifugation (10 min, 6000 g, 25° C.), pooled and resuspended in a total of 5 ml 3M NaCl. The suspension was vortexed vigorously and incubated for 15 min at ambient temperature to extract the surface-associated EPS. The cells were then re-pelleted (10 min, 5000 g, 25° C.) and the EPS-containing supernatant was retrieved. The supernatant was sterile filtered twice (0.45 μm followed by 0.2 μm), tested for sterility and stored at −20° C. until further use.

The S. cohnii isolate was restreaked on TSA, incubated for 3 days at 37° C., and used to inoculate an overnight culture (10 ml TSB+1% glucose, incubated at 37° C., 200 rpm). This culture was then diluted (1:100) into 250 ml fresh medium (TSB+1% glucose) in a Corning® CellBIND® 225 cm² Angled Neck Cell Culture Flasks with Vent Cap (Product #3293), and the flask was incubated at 37° C. for 2 days. The biofilm culture was pelleted by centrifugation (10 min, 8000 g, 25° C.), resuspended in 2.5 ml 3M NaCl and incubated for 30 min at room temperature. The cells were then re-pelleted (10 min, 5000 g, 25° C.), and the EPS-containing supernatant was retrieved, sterile filtered (0.20 μm, 16534-K, Minisart, Sartorius Stedim) and stored at −20° C. until use.

P. fluorescens was restreaked on TSA and incubated for 1 day at 20° C. The strain was inoculated into 10 mL of TSB and the culture was incubated statically for 16 hours at 20° C. After propagation, the culture was diluted (1:100) in 400 ml M63 supplemented medium (15 mM (NH₄)₂SO₄, 100 mM KH₂PO₄, 1.8 μM FeSO₄, 1 mM MgSO₄.7H₂O, 0.4% (w/v) glycerol, 0.2% (w/v) Casamino acids and 0.0001% (w/v) Thiamine), added to a Corning® CellBIND® 225 cm² Angled Neck Cell Culture Flasks with Vent Cap and incubated statically for 3 days at 20° C. The biofilm culture was subsequently pelleted by centrifugation (10 min, 8000 g, 25° C.), and the cells resuspended in 4 ml 3M NaCl and incubated for 30 min at 30° C. to extract the surface-associated EPS. The EPS-containing supernatant obtained after centrifugation (10 min, 5000 g, 25° C.) was then sterile filtered and stored at −20° C. until further.

A crude EPS extract from A. iwoffi was prepared as follows: The strain was restreaked on a TSA plate and incubated for 3 days at 30° C. 10 ml LB medium (L3152, Fluka) was then inoculated with a single colony, and incubated at 30° C., 200 rpm for 48 h. The culture was diluted (1:100) in 300 ml fresh LB, added to Corning® CellBIND® 225 cm² Angled Neck Cell Culture Flasks with Vent Cap and incubated statically for 4 days at 30° C. The biofilm culture was subsequently pelleted by centrifugation (10 min, 8000 g, 25° C.), and the pellet was resuspended in a total of 3 ml 3M NaCl and incubated for 30 min at room temperature. The EPS-containing supernatant obtained after centrifugation (10 min, 5000 g, 25° C.) was sterile filtered (0.20 μm, 16534-K, Minisart, Sartorius Stedim) and stored at −20° C. until use.

For wash performance testing, 50 ul aliquots of the different crude EPS extracts were spotted on sterile textile swatches (WFK20A) and incubated for 15 min at ambient temperature. The swatches (sterile or with EPS) were placed in 50 mL test tubes and 10 mL of wash liquor (15⁰dH water with 0.2 g/L iron(III) oxide nano-powder (544884; Sigma-Aldrich) with 3.33 g/L liquid model A detergent) and 0.2 μg/ml or 2 μg/ml enzyme was added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 37° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15⁰dH water and dried on filter paper over night. The tristimulus light intensity (Y) values were measured using a DigiEYE colour measurement and imaging system (VeriVide) equipped with a Nikon D90 digital camera, and are displayed in table 9.

Delta values (Y_((swatches washed with enzyme))−Y_((swatches washed without enzyme))) and relative wash efficiency values ((L_(With enzyme)−L_(No enzyme))/(L_(Sterile swatch)−L_(No enzyme))*100)) are also indicated.

The data clearly shows that the hexosaminidases show deep-cleaning properties against biofilm EPS from various microorganisms, including both gram-positive and gram-negative bacteria.

Example 9: Malodor Reduction of Hexosaminidase in Liquid Model Detergent

EPS were purified as described in e.g. example 8. After purification, 50 μL aliquots of EPS were added to the wells of 12-well polystyrene flat-bottom microplates (3512; Costar, Corning Incorporated, Corning, N.Y., USA), in which round swatches (diameter 2 cm) of sterile polyester (WFK30A) had been placed. The swatches were incubated for 15 min (static incubation) before proceeding. Six swatches were placed in 50 mL test tubes and 10 mL of wash liquor (15⁰dH water with 3.33 g/L liquid model A detergent) and 0.2 ppm, 2.0 ppm or 20.0 ppm enzyme (SEQ ID NO 9) were added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 37° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 20 mL 15⁰dH water and dried on filter paper over night.

Odor Chamber Setup and Analysis of Volatiles on Textile Using an Electronic Nose

To test for the binding of gaseous volatiles, all dried swatches were randomly distributed in a square plastic box (30.7 cm×21.9 cm×6.0 cm—inside measurements). In a 10 mL glass beaker position in the center, 5 mL of a mixture of various aldehydes (Pentanal 160 mM, Hexanal 40 mM, Heptanal 80 mM, (E)-2-Heptenal 20 mM, Octanal 30 mM, Nonanal 10 mM, Decanal 8 mM, (E)-2-Decenal 10 mM and (E,E)-2-Decadienal 12 mM—all chemical purchased from Sigma-Aldrich) were added. The odor chamber was closed with a lid and wrapped in Parafilm®. The swatches were incubated at room temperature for 16 h, before individually being placed in the bottom of 20 mL GC-MS vials (Mikrolab Aarhus A/S, Aarhus, Denmark) and capped with silicone screw top lids (Mikrolab Aarhus A/S, Aarhus, Denmark). From each sample 5 mL headspace was analyzed in a:

Example 10: Deep-Cleaning of Hexosaminidases in Different Detergents

A crude EPS (extracellular polymeric substances) extract was prepared from Pseudomonas fluorescens (Isolate from Iceland) as described in example 8. For wash performance testing, 50 ul aliquots of this extract were spotted on sterile textile swatches (WFK20A) and left to soak for 15 min at ambient temperature. The swatches (sterile or with EPS) were placed in 50 mL conical centrifuge tubes and 10 mL of wash liquor (15⁰dH water with 0.2 g/L iron(III) oxide nano-powder (544884; Sigma-Aldrich) and with detergent (3.33 g/L liquid model A detergent, 2.0 g/L model N or 4.6 g/L Persil Universal Gel®) was added. The enzyme was added to a final concentration of 0.2 μg/ml. Tubes without enzymes were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 37° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15⁰dH water and dried on filter paper over night. The tristimulus light intensity (Y) values were measured using a DigiEYE colour measurement and imaging system (VeriVide) equipped with a Nikon D90 digital camera, and are displayed in table 11.

Example 11: Wash Performance in TOM

A crude EPS extract was prepared from Pseudomonas fluorescens (Isolate from Iceland) as described in example 8. The extract was sterile filtered prior to use, and 100 μl aliquots were spotted on textile swatches (wfk20A (Polyester/Cotton mix (65%/35%)), 50 mm×50 mm), and incubated at room temperature for 10 min. The Terg-o-tometer wash was performed at follows; 0.4 g/L iron(III) oxide nano-powder (544884; Sigma-Aldrich) and 3.33 g/L liquid model detergent A was weighed out and left to soak for 1 h prior to the wash. The dirty detergent was then added to 1000 ml pre-warmed water hardness (15⁰dH) in the TOM beakers, and allowed to dissolve for 10 min (maximum agitation). The agitation level was then reduced to 90 rpm, and the textile swatches (two EPS swatches as well as ballast material (wfk10A, wfk30A) to reach a total of 10 g textile/beaker) were added and washed with or without enzyme (0.2 ppm) for 35 min at 30° C. After wash, all swatches were rinsed twice in tap water and dried on filter paper over night. The remisssion (REM^(460nm)) values were measured using a Macbeth Color-Eye 7000 (CE7000), and are displayed in table 12.

Delta values (REM^(460nm) _((swatches washed with enzyme))−REM^(460nm) _((swatches washed without enzyme))) are also indicated.

Example 12: Wash Performance in Full-Scale Wash

A crude EPS extract was prepared from Pseudomonas fluorescens (Isolate from Iceland) as described in example 8. The extract was spotted (200 μl aliquots) on a prewashed T-shirt (Anvil sustainable t-shirt (50% polyester/50% cotton)) that had been cut down the middle, and the spots were left to dry at room temperature for 30 min prior to the wash. The two halves of the T-shirt were washed independently in a Miele Laundry Washing Machine (Miele Softtronic, W2245) using tap water and 0.16 g/L iron(III) oxide nano-powder (544884; Sigma-Aldrich) in 3.33 g/L liquid model A detergent. The 40° C. Color program was used (run time 1 h, 26 min). After wash, the two halves of the T-shirt were hang-dried at room temperature overnight. The remisssion (REM^(460nm)) values were measured using a Macbeth Color-Eye 7000 (CE7000), and are displayed in table 13. Delta values (REM^(460nm) _((swatches washed with enzyme))−REM^(460nm) _((swatches washed without enzyme))) are also indicated.

Example 13: EPS Hydrolysis Measurements Using Fluorescent WGA-Alexafluor488 Assay

The Pseudomonas fluorescens strain isolated from Iceland was used as model microorganisms in the present example. The Pseudomonas fluorescens strain was restreaked on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131; Oxoid Ltd, Basingstoke, UK) and incubated for 1 day at 23° C. The strain was inoculated into 10 mL of TSB and the culture was incubated with shaking for 16 hours at 23° C. The overnight culture was diluted (1:100) in 200 ml M63 supplemented medium (15 mM (NH4)2SO4, 100 mM KH2PO4, 1.8 μM FeSO4, 1 mM MgSO4.7H2O, 0.4% (w/v) glycerol, 0.2% (w/v) Casamino acids and 0.0001% (w/v) Thiamine) added to a Corning® CellBIND® 225 cm² Angled Neck Cell Culture Flask with Vent Cap (Product #3293) and incubated statically for 5 days at 23° C. Each biofilm culture was subsequently transferred to four 50 ml falcon tubes (Corning #430820) and pelleted by centrifugation (10 min, 8000 g, 25° C.), and the supernatants were discarded completely. The residual pellets from each of the four falcons were resuspended in 0.450 ml 3M NaCl to extract the surface-associated EPS (extracellular polymeric substances) and pooled in one test tube (5 ml, Eppendorf #0030119401). The suspension was centrifuged at 5000 g for 10 min at 25° C. and the 1.8 ml supernatant was transferred to a new test tube as EPS fraction and stored at −20° C. until further use (termed crude EPS). 150 ul aliquots of the crude EPS were dispensed in three Eppendorf tubes and mixed with 150 ul of an enzyme solution containing 80 ppm of either SEQ ID NO 9 or 50 mM Hepes100 mM NaCl buffer alone and incubated 1 hr at room temperature. 50 ul aliquot samples were retrieved from each tube and then added to the wells of a nunc Maxisorp black microtiter plate (ThermoScientific #437111) in which round swatches of sterile prewashed swatches (wfk 20A, polyester/cotton 65%/35%) had been placed. The plate was incubated at room temperature for 15 minutes. Supernatants were then removed from each well and swatches were washed with 100 ul water. Next, 50 ul of WGA-Alexa fluor488 dye (10 ug/ml; excitation/emission maxima ˜495/519 nm; Thermo Fischer Scientific, #W11261) was added to each well. Alexa Fluor® 488 WGA binds to sialic acid and N-acetylglucosaminyl residues. The plate was incubated at room temperature for 15 min. Samples were finally washed with 100 ul water and measured in the SpectraMax M3 instrument. Each of the three samples corresponding to the crude EPS mixed with the enzyme solutions and buffer control, were tested on 8 swatches placed in 8 wells. The measurements obtained including the standard deviations are listed below in table 14.

Results from the fluorescent measurements show that the EPS extract from the P. fluorescens strain is labelled with WGA-Alexa Fluor488 suggesting that the EPS contains N-acetylglucosaminyl residues and is sensitive to hexosaminidase (SEQ ID NO 9) hydrolysis.

Example 14: Wheat-Germ Agglutinin (WGA)-Staining of Washed EPS Swatches

A crude EPS extract was prepared from Staphylococcus aureus 15981 (kind gift from Iñigo Lasa (Valle, J., A. Toledo-Arana, C. Berasain, J. M. Ghigo, B. Amorena, J. R. Penades, and I. Lasa. 2003, Mol. Microbiol. 48:1075-1087) as described in example 8 with minor modifications: The culture was incubated for 24 h at 37° C. in TSB+1% glucose prior to EPS extraction. For washing, 100 ul aliquots of the EPS were spotted on sterile textile swatches (prewashed wfk20A textile, 65% Polyester/35% Cotton) and incubated for 20 min at ambient temperature. The swatches (sterile or with EPS) were placed in 50 mL test tubes and 10 mL of wash liquor (15⁰dH water with 3.33 g/L liquid model A detergent) and 20 μg/ml enzyme was added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 37° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15⁰dH water and placed in a 12-well polystyrene flat-bottom microplate (3512; Costar, Corning Incorporated, Corning, N.Y., USA). The swatches were then stained with Alexa Fluor® 488 Conjugated Wheat Germ Agglutinin (WGA) (10 μg/ml in 1×PBS) for 30 min at room temperature, rinsed twice with 1×PBS and measured by well-scanning in a BMG CLARIOstar microplate reader (Excitation at 488 nm, emission at 525 nm). The fluorescence intensity values are shown in table 15.

The relative substrate removal compared to the control (FIU_(with enzyme)−FIU_(without enzyme)) is also shown.

When WGA lectin has affinity for N-acetylglucosaminyl residues, the results shows that the hexosaminidase treatment improves substrate removal from the textile during the wash.

Example 15: Construction of Clades and Phylogenetic Trees

The Glyco_hydro_20 domain includes the polypeptides of the invention having hexosaminidase e.g. PNAG activity and comprises the WND domain as well as the clusters such as the clades. A phylogenetic tree was constructed, of polypeptide sequences containing a Glyco_hydro_20 domain, as defined in PFAM (PF00728, Pfam version 31.0 Finn (2016). Nucleic Acids Research, Database Issue 44:D279-D285). The phylogenetic tree was constructed from a multiple alignment of mature polypeptide sequences containing at least one Glyco_hydro_20 domain. The sequences were aligned using the MUSCLE algorithm version 3.8.31 (Edgar, 2004. Nucleic Acids Research 32(5): 1792-1797), and the trees were constructed using FastTree version 2.1.8 (Price et al., 2010, PloS one 5(3)) and visualized using iTOL (Letunic & Bork, 2007. Bioinformatics 23(1): 127-128). The polypeptide sequences containing a Glyco_hydro_20 domain comprises several motifs; one example is GXDE (SEQ ID NO 18), situated in positions 158 to 161 in Terribacillus saccharophilus (SEQ ID NO 9). Residues D and E are the key catalytic residues of Glyco_hydro_20 enzymes (position 160 to 161 in SEQ ID NO 9).
